MINEOLA, N.Y. (AP) — For years, the thicket along a beach highway on Long Island held a horrible secret. Hidden from passing drivers were the skeletal remains of 10 people, mostly young women who had worked as prostitutes. Who killed them, and why, is a mystery that has vexed a slew of seasoned homicide detectives.The case took an intriguing turn when a veteran county prosecutor became the first authority to publicly name a suspect in at least one of the deaths: John Bittrolff, a Long Island carpenter who was sentenced to consecutive 25 years-to-life terms in prison this week for beating two prostitutes to death in 1993 and 1994.
